With Lagercrantz's first two installments, the Millennium series had sold over 100 million copies worldwide by May 2019, making it one of the best-selling book series in history.

The Girl in the Spider's Web was published in 2015, followed by The Girl Who Takes an Eye for an Eye in 2017, and The Girl Who Lived Twice in 2019. In 2013, Norstedts Förlag commissioned Swedish author and crime journalist David Lagercrantz to continue the Millennium series with Larsson's characters. By March 2015, 80 million copies of the first three books had been sold worldwide. The books have since been translated by many publishers in over 50 countries. Knopf in the United States translated by Steven 'Reg Keeland' T. Larsson's novels were originally printed in Swedish, with English editions by Quercus in the United Kingdom and Alfred A. All three were published posthumously by Norstedts Förlag: The Girl with the Dragon Tattoo in 2005, The Girl Who Played with Fire in 2006, and The Girl Who Kicked the Hornets' Nest in 2007. Larsson planned the series as having 10 installments, but completed only three before his sudden death in 2004. The two primary characters in the saga are Lisbeth Salander, an asocial computer hacker with a photographic memory, and Mikael Blomkvist, an investigative journalist and publisher of a magazine called Millennium. Millennium is a series of best-selling and award-winning Swedish crime novels, created by journalist Stieg Larsson.
